HVAC

High Efficiency Central Air Conditioners are measured by Seasonal Energy Efficiency Ratio (SEER). When comparing different AC units, use the SEER rating to determine which unit is rated most efficient; the higher the SEER rating, the higher the efficiency level of the unit. Higher efficiency equals lower bills. For example, switching out an old 8 SEER unit with a properly installed 16 SEER unit can reduce your monthly energy cost by nearly 50 percent.

Rebate amounts vary depending on the SEER rating:

Rebate Application Requirements:

• AC unit must be installed by a registered contractor. Search for a registered contractor.
• Submit Energy Efficient HVAC Rebate Application, invoice, AHRI certificate, and a Quality Installation Program Application completed by the contractor to ERMU by mail or email at customerservice@ermumn.com.

Air Source Heat Pumps (ASHPs) provide home cooling and supplemental heating with 72 percent less electricity than conventional air conditioners and furnaces. You can switch between cooling and heating directly from the thermostat, putting you in complete control.

Rebate amounts vary depending on the SEER rating:

Rebate Application Requirements:

• ASHP must be installed by a registered contractor. Search for a registered contractor.
• Submit Energy Efficient HVAC Rebate Application, invoice, AHRI certificate, and a Quality Installation Program Application completed by the contractor to ERMU by mail or email at customerservice@ermumn.com.

Ductless Air Source Heat Pumps (ASHPs) make excellent retrofit add-ons to homes with non-ducted heating systems. They can also be a good choice for room additions where extending or installing ductwork isn't feasible. An outdoor condenser connected to individually controlled indoor units allows for zoned heating and cooling, which maximizes comfort and energy savings.

ERMU offers rebates on the following ASHPs with a SEER rating of 16 or higher: $400 for homes heated by natural gas, propane, or fuel oil, and $600 for homes heated by electric.

Rebate Application Requirements:

• Submit Energy Efficient HVAC Rebate Application and invoice to ERMU by mail or email at customerservice@ermumn.com.

An electronically commutated motor (ECM) helps save energy and money by running your furnace at the best speed possible, versus a traditional motor that always runs the fan at top speed. Because your furnace fan distributes air in your home for both the heating and cooling season, an ECM helps save you money throughout the year.

ERMU offers a $150 rebate towards the purchase of a new furnace with an ECM, or a $100 rebate for retrofitting an existing furnace with a ECM.

Rebate Application Requirements:

• Submit Energy Efficient HVAC Rebate Application, invoice, and AHRI certificate to ERMU by mail or email at customerservice@ermumn.com.

Ground Source Heat Pumps (GSHPs) take advantage of the consistent temperature underground. In the winter, heat is pumped out of the ground and transferred to the air in your home, and in the summer, the process is reversed. Combining heating and cooling into one convenient unit, GSHPs operate with 300 to 400 percent efficiency, giving them a higher return on investment than any other technology.

ERMU offers a $600 per ton rebate on closed loop ground source heat pumps. Open looped systems do not quality for rebates.

Rebate Application Requirements:

• Submit Energy Efficient HVAC Rebate Application and invoice to ERMU by mail or email at customerservice@ermumn.com.

A WiFi thermostat offers temperature control, in-depth reporting, alerts, and energy savings all at the touch of a button.

ERMU offers a $40 rebate for a WiFi-compatible thermostat.

Rebate Application Requirements

• Submit WiFi Thermostat Rebate Application and a copy of the receipt to ERMU by mail or email at customerservice@ermumn.com.
• Limit of two rebates per service address.
